Crystals are responsible for controlling the frequency at which electronic devices, such as radios, TVs, and computers, operate, and they become increasingly important components in many of today’s electronic applications.

The HC-49/U-S4915200ABJB is one of the many types of crystals available. This crystal is ideal for applications that need to maintain an accurate frequency with minimal power consumption. It has an improved electrical performance and a low profile which makes it suitable for applications where space and influence on the component layout are major considerations.

The working principle of the HC-49/U-S4915200ABJB crystal is based on the quartz crystal oscillator. In this type of oscillator, a quartz crystal is mounted between two metal plates to form a parallel plate capacitance with the crystal acting as the dielectric material. When an alternating voltage is applied to the plates, the vibration of the crystal produces an oscillating current as the electric field within the crystal is continually changing.

The oscillating current gives rise to an electrical field in the crystal which in turn produces a mechanical vibration within the crystal. The mechanical vibration of the crystal is then amplified by the two metal plates and the resulting oscillation is collected from the two output terminals of the crystal.

The HC-49/U-S4915200ABJB crystal is particularly suitable for applications that require an oscillation frequency between 20 kHz and 80 MHz, with a standby current consumption of less than 2 mA. Its low profile makes it particularly suitable for use in portable devices, as well as applications where space is a major consideration. It is also suitable for a wide range of operating environments, including automotive, automotive/telecom and medical.

The HC-49/U-S4915200ABJB crystal can also be used in combination with other components, such as resonators, to create more complex systems. For example, the crystal can be used with a fixed resistor to form an LC (inductor-capacitor) circuit, which can be tuned to a specific frequency, or a specific range of frequencies. This type of circuit is commonly used in communications, wireless and medical systems.

In addition, the HC-49/U-S4915200ABJB crystal can be combined with a Power Management IC (PMIC) such as the Cypress PMIC to create a complete frequency control system. The PMIC can then be used to control the frequency of the crystal, from low to high, in order to make sure that the device is operating at the correct frequency. This type of system is commonly found in applications such as Smartphone or TV.

The HC-49/U-S4915200ABJB is an ideal choice for a wide range of applications and its small size, low power consumption and improved electrical performance make it suitable for a broad range of applications from low frequency to high frequency communication and medical systems.
